I am an engineer and nuclear physicist, have founded two Inc. 500 fastest growing companies, have been involved in over 50 entrepreneurial ventures and now edit four investment newsletters at The Arora Report. The credit for my enviable performance record goes to my highly analytical method designed to predict change before Wall Street.

All four services utilize my ZYX Change Method. The premise behind the ZYX Change Method is that the most money is made with the lowest risk by successfully predicting change before the crowd. Free no risk 30 day trials are available for all four services.

I have combined my strong mathematics background with extensive global business and change management experience to develop the ZYX Change Method. The method is the culmination of 25 years of experimentation with a variety of investment models under both bull and bear markets.

Samsung's New 5G Breakthrough Points To Long Term Risks For Apple

A report from South Korea’s Yonhap News Agency about Samsung offering 5G service by 2020 caught my eye. Speculation about 5G abounds, so the title was not a surprise. What was intriguing to me was a claim of transmitting data in the millimeter wave band to a distance of two kilometers.

My initial interest was due to my electrical engineering background, I always thought that millimeter wave band was not suitable for long distance transmissions. There is significant atmospheric attenuation in this band.

The news agency report did not tell me much but subsequent information from Samsung shed some light. Samsung used a frequency of 28 GHZ. This frequency is close to the lower band of the highest radio frequency band known as extremely high frequency which goes from 30 to 300 GHZ. Samsung used an adaptive array transceiver using 64 antenna elements to obtain a speed of up to 1.056 Gbps to transmit the signal up to two kilometers. Samsung claims that its transceiver technology overcomes large atmospheric attenuation. There are not many other details and I still cannot figure it out exactly how Samsung did it. In any case, the important point is not my inability to figure out how Samsung did it but the fact that Samsung is confident enough to make this claim.

More astounding is Samsung’s claim that 5G will offer transmission speeds of tens of Gbps, contrast this with a test that achieved a speed of only 1.056 Gbps. To say the least I remain skeptical even though the media is eating from Samsung’s hands without questioning the details. Here is a statement from Samsung for public consumption,

Samsung ElectronicsSamsung Electronics announced that it has successfully developed the world’s first adaptive array transceiver technology operating in the millimeter-wave Ka bands for cellular communications. The new technology sits at the core of 5G mobile communications system and will provide data transmission up to several hundred times faster than current 4G networks…5G mobile communications technology is the next generation of the existing 4G Long Term Evolution (LTE) network technology. 5G will be capable of providing a ubiquitous Gbps experience to subscribers anywhere and offers data transmission speeds of up to several tens of Gbps per base station.”

From an investment perspective, this development highlights the very long-term risks to AppleApple. While Samsung is busy inventing breakthrough technology that may someday allow data transmissions at 100 times the speed of 4G, what basic technology breakthrough has Apple announced lately? It is true that Apple will be able to license a 5G technology that comes to fruition in the commercial space. Samsung is not the only one working on 5G. But it is important to note that Samsung has already successfully countered Apple in the global patent war with some of its patents on transmission technologies.

The farther ahead Samsung gets in terms of important patents on new data transmission technologies that may someday become the core of 5G; the more troubling it will be for Apple.
